break through the nuclear membrane, after which the fibers which 
connect the chromosomes straighten out and the groups of chromo- 
somes are carried far beyond the limits of the nucleus (fig. 42). 
The nuclear membrane then breaks down. The nucleolus is left

connect the centrosomes and those which radiate out into the 
cytoplasm frequently persist until after nuclear membranes have 
been formed around the daughter nuclei (fig. 45). Sometimes the 
groups of chromosomes are not separated so far, and in this case 
the daughter nuclei may reorganize in contact with each other.
